The speedometer is a road indicator. The vehicle speed sensor (VSS) is a permanent magnet generator which is located on the transaxle. The VSS sends an input to the PCM whenever the transaxle differential carrier turns. The PCM then buffers the VSS signal. The PCM transmits the VSS signal to the following components at 4000 pulses/mile through CKT 817:
• The instrument cluster
• The cruise control module
• The radio (uplevel)
The instrument cluster uses the input in order to indicate the vehicle speed on the speedometer.
Instrument Cluster Indicators
The BCM controls the instrument cluster indicators through the SPI serial data communication bus. Refer to Body Control Module System Check in Body Control System.

All of these gauges are digital are controlled by a computer in the instrument cluster. You will need to remove the cluster and send it out for repair by a factory approved instrument cluster repair center. You can find these on line. JUst Goggle "Dodge Instrument Cluster repair"
This is a ground problem. There are cluster grounds on the bolts that bolt the engine and trans together. You will have two of them one in the front under the front engine mounting bracket and one towards the back of the car almost right under the EGR. This is a common problem and requires a quite a bit of time to get to the two bolts to clean the connections on the grounding clusters. I ran into this problem after replacing my engine and it took me several hours before I finally found this problem. Good luck!
The light behind myRemove the cluster bezel from the instrument panel. See Cluster Bezel in this group for the procedures. Remove the four screws that secure the instrument cluster to the instrument panel Instrument Cluster Remove/Install Pull the instrument cluster rearward to disengage the two self-docking wire harness connectors NOTE: The instrument cluster has two self-docking wire harness connectors that will be automatically aligned with, and connected to the instrument panel wire harness when the cluster is installed in the instrument panel. Remove the instrument cluster from the vehicle. Reverse the removal procedures to install. Tighten the mounting screws to 2.2 N·m (20 in. lbs.) when I turn my headlights on. All the other gauges are lit, but not the gas gauge. How do I get in there to replace the bulb and fix this? Or is it a fuse problem? I have a 1998 jeep scout Thanks
